Full title and description

ISO 6883:2017 — Animal and vegetable fats and oils — Determination of conventional mass per volume (litre weight in air). This International Standard specifies a laboratory procedure for determining the conventional mass per unit volume of liquid animal and vegetable fats and oils so volume and mass can be converted reliably for trade, analysis and quality control purposes.

Abstract

ISO 6883:2017 specifies a method for the determination of the conventional mass per volume ("litre weight in air") of animal and vegetable fats and oils (applicable only when the fats are in a liquid state). Milk and milk products (and fats derived from them) are excluded. The standard notes that the oscillating U‑tube method for density determination is covered in ISO 18301.

General information

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 67.200.10 (Animal and vegetable fats and oils).
• Edition / version: Edition 5 (2017).
• Number of pages: 11 pages (ISO edition information).

Scope

Specifies a laboratory method to determine the conventional mass per volume (litre weight in air) of animal and vegetable fats and oils when in the liquid state, for the purpose of converting between volume and mass. The procedure excludes milk and milk products (and fats from those products). The standard also references the oscillating U‑tube method (ISO 18301) as an alternative density determination technique.

Key topics and requirements

• Definition and expression of "conventional mass per volume" (litre weight in air) for fats and oils.
• Specified laboratory procedure for measuring mass per unit volume of liquid fats to enable reliable mass/volume conversions.
• Requirements for sample condition (liquid state) and exclusions (milk and milk products).
• Reference to alternative measurements methods (oscillating U‑tube — ISO 18301) where applicable.
• Measures to control test conditions (temperature control, repeatability/accuracy considerations and calculation of results for reporting).

Typical use and users

Used by analytical and testing laboratories, quality control teams in edible‑oil and fat production and processing, food manufacturers, commodity traders and regulatory bodies for trade, specification compliance and laboratory reporting where reliable conversion between mass and volume of fats and oils is required. National standards bodies and testing laboratories commonly adopt the ISO method as an EN/BS/DIN adoption.

Related standards

ISO 18301 (oscillating U‑tube method for density) is referenced as an alternative method for determining conventional mass per volume. The standard was prepared under ISO/TC 34/SC 11 (foods and animal/vegetable fats and oils) and replaces the earlier ISO 6883 editions (for example ISO 6883:2007, withdrawn).

FAQ

Q: What is this standard?

A: ISO 6883:2017 is an International Standard that defines a laboratory method to determine the conventional mass per unit volume ("litre weight in air") of liquid animal and vegetable fats and oils, enabling conversion between mass and volume.

Q: What does it cover?

A: It covers the test procedure, specimen condition (only liquid fats), reporting of results and notes the exclusion of milk and milk products. It also refers users to ISO 18301 for the oscillating U‑tube density method.

Q: Who typically uses it?

A: Analytical laboratories, food and edible‑oil industry QC teams, commodity traders, standards bodies and regulators who need consistent mass/volume conversions for fats and oils.

Q: Is it current or superseded?

A: ISO 6883:2017 is the current published edition (2017) and the 2007 edition was withdrawn and replaced by the 2017 edition. The 2017 edition was reviewed/confirmed in subsequent ISO reviews (confirmed status noted by ISO).

Q: Is it part of a series?

A: It is part of ISO/TC 34/SC 11 deliverables on methods for analysis of animal and vegetable fats and oils; related density/mass methods (e.g., ISO 18301) and other ISO test methods for fats and oils form the broader family of analytical standards in this sector.

Q: What are the key keywords?

A: Conventional mass per volume, litre weight, density, fats, oils, pyknometer, oscillating U‑tube, mass/volume conversion, ISO 18301.
